cUL'TivAToR- ATTACHMENT.

Application led October 1, 1926*.k Serial No: 138,975.-

This invention, relatesfto-r a cultivator attachment, andhas for its object to provide, in a manner as' hereinafter set forth, an attachment for use inl connection withl a cultito growing fruit trees-or plantsand vines of a grape vineyard; and further enabling an operator tol work in closeto and in and out aroundfa tree or plant, accomplishing in one operation, whaty ordinarilyV callsv for three, viz z-riding cultivator, single cult-ivator kand furrowing.

A further objectA of the inventionY is tov provide in a manner as hereinafterset forth, a cultivatorl attach-menty for riding culti- 'vatorsgoperatingbetween one wheel ofthe latter andthe growing tree,- plantl or vine and adaptedwhen used to vdispense entirely with asingle cultivator and reducing the hoeing ordinarilyy required during cultivation yto a-minimum. v

Eurtherobjects of the invention are to provide, in a-manneras hereinafter set forth, a Acultivator attachment, termed-fan extension gang, which islsi-mple in its-construction and arrangement, strong, durable, compact, tl'ioroughlyefticient in it'suse, conveniently installed with respect t-o a riding cultivator andv comparatively inexpensiveto manufacture. Y

l with the foregoingvv and other objects in view, theinvention consistfsof the novel-foonstruction, combination andf arrangement l of parts-as hereinafter more specificallyA lde scribed, andillustrated in the accompanying drawing wherein is shown an embodiment Vof the `invention, butit-is to -be Vunderstood lthat changes, variations and modifications can beresortedtol which-fall within vthe scope` of the claims hereunto appended;

In 'the drawings wherein likenreference characters denote correspondingV4 parts throughout-the several views:-'- v Figure 1 is a side elevation ofa riding-cul- "tivator, of the pivoted axleV type showlng the adaptation therewith-of-an attachment, termedfanf extension gang,- in vaccordance with this'inventio'n. w

Referring tothe' drawings'indetail Agenerally indicatesv a riding cultivator' loffthe type includingl an agile-providedwithl a pair of shiftable vspindles upon wlnchlare revolublyrnou'nted the side wheelss The 'cultivator A further includes a gangor gangs and a drag bar therefor. The cultivator'isillustrated for'the purpose ofrshowing the adaptation-therewithr of' an attachment extension gan-g, in accordance with this invention, and

no'claim islmade to any ofthe elementsof the cultivatorA;

An attachmentI for' cultivators, in: `accordance with this invention, and which is termed an extension gang,- wh'en coupled with the cultivator operates 'between one-of the wheels of the latter and-,the tree or plant andlas Vshown the extension is coupled with the forward portion lofE the culti'vator frame, asat 2, and with acultivator-gang as at 3.

The attachment includes an upwardly and forwardly inclinedl combined carrier iand 'coupling' element` referred to' generally by the reference characterll landwhich is constructed from. ametallic barl of'appropriate length, Width'and thickness. The bar from which theelement 11 is constructed isshaped to forma forward arm 12, an inner rearward-ly directed armnl?)` and an outer-rearwardly .directedf'arm V14k of materially greater length-from -the arm 13 andV which: has its Vrearend-curved'upwardly and inwardly as .ati15=to.form'what'may be termed aa guide,

protector `or deflector. The forward i'arm` 12 ofthe-element 11 is'of'greaterlength than l the length ofthe arm r13, but ofrless length than4A the'arm 14;. Therearwardly directed arms 13 and lemerge attheir forward ends into the ends of'the forward arm l2. lhen the l attachment is coupled: with the cultivator A, the-forfwardarm 12'of1fthe'element '11 is `positioned a substantialY distance above thehu'b ofyfandforwardly with respect to the wheel 1f ofV the-lcultivator" A whichsaid eleinent istradd'les the forward-p art of.-V The armlfl when the element is coupled withv the cultivator, h'asits'lower end spaced a sub- -stantial 'dista-nce above the ground level.

Positioned against thein'ner-,side face of the arm 14 of'the element 11, intermediate the ends ofsaid arm 14;, isa yoke-shaped member, referred-:to generally by the reference character 16 fand which is disposed longitudinally with respect to the'portionlt. vvThe member liincludesa basel which is arranged aat'right iangleswith respect to the Varm-14=` ofthe element v11 andjsaid member 'further-includes afpalr Yof side arms 18,l 19 'and-'with' the latterofgreater lengthithan the former;- Th'e arm-19 is fixed-lyy secured to the inner face of the armvl/.ifand'thearm 1S extends :forwardly and at an outward in clination so as to project towards the arm 19. The arms itl and 1S) project forwardly and upwardly from the base 17 and the latter is disposed at a downward and rearward inclination. The arm 19 is secured against the inner side tace of the arm 1-1 by a hold fast device 19. The arm 19 is also secured to the arm 1i by a hold tast device 20, but this latter further coupled with the arm 1.9 and arm irl of the element 11, the 'forward end of a rearwardly extending and downwardly inclined angleshaped brace member 21 which has its rear end lined by the hold tast device 3, to a standard of a gang of the cultivator. The arm 13 ot the element 1.1 is lixedly secured to the cultivator trame by the hold tast devices 2.

Secured to the arm 1 2 o t the element 11, and also to the arm 1S is a combined gniard and brace elem-ent, referred to generally by the reference character and which is constructed from a. metallic bar iforined ot a curved rear portion 25 which constitutes a wheel guard and a. torsionally twisted torward portion QG which constitutes a brace between the member 15 and the element 1l. 'lhe rear portion ot the element eX- tends` inwardly from the member 1G. The forward portion 2G ot the element secured by the hold tast device 2T to the arm 18 of the member 1G and is itormed with a flange 2t which is secured by the hold tast device Q8 to the portion 1Q of the arin 11.. The combined guard and brace element is disposed at an upward inclination, it extends rearwardly from the arm 12 of the element 11 and at an inward inclination with respect to the arm 1st of the element 11.

Secured to the inclined base 17 oit the member 1G, by the hold tast devices 29 is a plurality ot' curved resilient standards 30 each proifidcd with a cultivating element Si adjustably connected therewith as at The standards 30, with respect to the inember 1G entend upwardly and rearwardly therefrom and downwardly7 and the lower portion of each is of polygonal contour, as at 33, and upon which is adj'ustably connected the cultivating` member or element 31.

dien the attachment is coupled with the cultirator A, the guard is arranged in close proximity to the wheel of the cultivator which is straddled by the element 11. The brace member 21 extends between a pair oit standards 30. The arm 14C has the lower portion thereof arranged outwardly with rcspect to the outer cultiyator or member 3l of the attaclnnent` and the curved lower terminal portion ot the arm itt opposes and extends rearwardly from said outercultiyating element 31. The length of the arm 12 of the element 11 is such as to maintain the cultivating elements 31 a substantial distance, from the wheel of the cultivator A,

Leaaaoo when the attachment is coupled with the latter. tthe attachment is adjustably con nected to the cultivator.

.lt is thought the many advantages ot a cultivator attachment, termed an extension garni'y in accordance with this invention can be readily understood, and although the preterrcd embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of con struction can be had which will tall within the scope oi the invention as claimed.

lrhat l claim iszvy l. il. cultivator attaclnnent comprising a eubstanitially yoke-shaped combined carrier and coupling element adaliited to be secured with the cultivator in overlaiupingl position with respect to a wheel olf the latter and turther to project forwardly and at an upward inclination with respect to the wheel, a rearwai-illy extending; brace member having,` its toi-wa rd end connected to said u'irdiate the ends oit the latter and adapted to have its rear end secured to a gang ot the cultirator, a sapport-ing` member arranged within and connected to said element inten mediate the ends oi the latter, a. combined guard and brace member secured to said element and suplmrtinp` member and extendingl rearwardly from the latter at a downward inclination, ground working` means posi tioned exteriorly of the cultivator wheel and secured to and extended rearwardly from said supportingv member, and said carrier having the rear end thereot' at its outer side upwardly and inwardly curved forming a guide opposingl the outer side of said means.
